The low-temperature coolant circulation pump is a low-temperature liquid circulation device that uses mechanical cooling.
It has the function of providing low temperature liquid bath and low temperature water bath.
Combined with a rotary evaporator, vacuum freeze-drying oven, circulating water vacuum pump, magnetic stirrer and other instruments, it can perform multi-functional low-temperature chemical reactions and drug storage.
Low temperature coolant circulation pump failure analysis:
The cooling speed seems to be getting slower and slower, and it is more obvious when the temperature is higher?
The low-temperature coolant circulation pump is very easy to operate, but regular maintenance work must not be neglected.
There are many problems that seem to be buggyft, but are in fact due to non-regular maintenance.
The flow of the low-temperature refrigerant circulation pump itself and the heat that the refrigerant extracts from the cargo must be removed from the radiator at the front ventilation hood;
If the front ventilation hood is full of dust and willow cotton, etc., it will hinder the distribution of this heat and the cooling effect will be greatly reduced.
In general, under normal usage conditions, the cooling performance decreases because the ventilation and heat dissipation effect are too poor or the ambient temperature is too high.
When using the low temp coolant circulating pump, noticed that the noise is much louder than before.
I mentioned the daily maintenance of the low temp coolant Circulation pump, this problem is also related to it.
As we all know, the water contains very few impuritiesments Even if distilled water is added to the water tank, it cannot be fully guaranteed that there are no impurities at all.
For the water circulation of the low-temperature coolant circulation pump, the general temperature is adjusted to 20°C, which is particularly suitable for the growth and reproduction of microorganisms.
After a long time, these microorganisms will clog the filter of the water path, resulting in bad return water and the water pump will make a lot of noise.
Sometimes these microorganisms adhere to the surface of the heat exchanger, causing the heat transfer efficiency of the heat exchanger to deteriorate and the cooling performance to decrease.
Therefore, be sure to carry out the daily maintenance work in strict accordance with the requirements in the manual, regularly clean the inner tank, do not use it for a long time, and keep the tankdry.
